SpaceX Unveils 'V2 Mini' Starlink Satellites With Quadruple the Capacity
An anonymous reader quotes a report from Ars Technica: With Starlink speeds slowing due to a growing capacity crunch, SpaceX said a launch happening as soon as today will deploy the first "V2 Mini" satellites that provide four times more per-satellite capacity than earlier versions. Starlink's second-generation satellites include the V2 Minis and the larger V2. The larger V2s are designed for the SpaceX Starship, which isn't quite ready to launch yet, but the V2 Minis are slimmed-down versions that can be deployed from the Falcon 9 rocket. "The V2 Minis are smaller than the V2 satellites (hence the name) but don't let the name fool you," SpaceX said in a statement provided to Ars yesterday. "The V2 Minis include more advanced phased array antennas and the use of E-band for backhaul, which will enable Starlink to provide ~4x more capacity per satellite than earlier iterations." SpaceX didn't specify the amount of data that each V2 Mini satellite can provide, but its first-generation satellites were designed for an aggregate downlink capacity of 17 to 23Gbps per satellite. The Federal Communications Commission recently gave SpaceX approval to launch 7,500 of the 30,000 planned second-generation satellites. A SpaceX Falcon 9 launch tentatively scheduled for today would put 21 V2 Minis into orbit. The larger V2 satellites that can't launch until Starship is ready will be able to send signals directly to cell phones, a capability that'll be used by SpaceX and T-Mobile in a partnership announced in August 2022. "Each Starlink V2 Mini satellite weighs about 1,760 pounds (800 kilograms) at launch, nearly three times heavier than the older Starlink satellites," notes Spaceflight Now. "They are also bigger in size, with a spacecraft body more than 13 feet (4.1 meters) wide, filling more of the Falcon 9 rocket's payload fairing during launch." UPDATE: SpaceX successfully launched the first batch of "V2 Mini" Starlink satellites. "A Falcon 9 rocket hauled the 21 Starlink satellites into a 230-mile-high (370-kilometer) orbit after lifting off from pad 40 at Cape Canaveral Space Force Station at 6:13:50 p.m. EST (2313:50 GMT) Monday," reports Spaceflight Now. "SpaceX delayed the launch from earlier Monday afternoon to wait for radiation levels to abate following a solar storm that sparked dramatic auroral displays visible across Northern Europe and Canada." You can watch the launch here. Elon Musk also shared video of the first V2 satellites to reach orbit.
